SPECIFICATION forming part of Letters Patent No. 784,283, dated March '7, 1905.

Application filed May 12, 1904. Serial No. 207,660.

To (1 7 7 whom it 'lI'L/bj/ concern.-

Be it known that 1, CHARLES HENRY SMITH, a citizen of the United States, residing atRichmond, in the county of I-Ienrico and State of Virginia, have invented a new and useful Nozzle, of which the following is a specification.

This invention relates to devices employed for controlling the flow of water or other liquid through the nozzles of tire-hose, and has for its object to simplify and improve the construction and produce a device of'this character which may be quickly applied to any of the various sizes and forms of nozzles manufactured and by means of which the strength of the stream passing through the nozzle may be easily controlled or cut off entirely by the operator without changing his position or releasing his hold upon the hose or nozzle.

\Vith these and other objects in view,which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages, and the right is therefore reserved of making all the changes and modifications which fairly fall within the scope of the invention and the claims, made therefor.

In the drawings, Figure 1 is a side elevation of the improved device applied. Fig. 2 is an enlarged longitudinal section of the improved attachment. Fig. 3 is a transverse section of the same. Fig. 1 is a bottom plan view with the lower cap removed.

In this improved device is comprised a hose nozzle 10, a nipple 11, connected to the discharge end of the hose 12, and an improved cut-off and controlling device coupled between the nozzle and nipple in convenient position for the operator, who may thus manipulate the device with the same hand which supports the nozzle and without releasing his grip therefrom.

The improved attachment comprises a casing 13, closed at one end and with a detachable threaded closing-cap 14 at the other end. The interior of the casing 13 is formed into a circular valve-seat and has the nozzle connection 15 and nipple connection 16 at opposite sides, so that when coupled between the nozzle and nipple the flow of water will be uninterrupted when the valve is open. Mounted for rotation through the closed end of the casing 13 is a valve-stem 17, having a handwheel 18 upon its outer end and a stul'liugbox 19 to secure a water-tight joint between the stem and casing. The valve is of peculiar and novel construction and consists of a relatively thin and flexible seat-engaging portion 20 and a lateral wing 21 for detachable engagement with the inner end of the valvestem, as by a binding-nut 22. The area of the portion 20 of the valve is suiiiciently greater than the area of the aperture leading to the nozzle to entirely cut oil the flow of water when set in one position, but will ontirely open the aperture and permit an uninterrupted flow of liquid when set in the opposite position, and it will be obvious that the amount of the flow can be easily controlled by adjusting the valve to any intermediate point.

The portion 20 of the valve being comparatively thin and flexible and the pressure being constantly against its rear side will cause it to be tightly compressed upon its seat and by its flexibility will etl'ectually seat itself thereon and prevent leakage. The flexible valve will thus become self-seating in its action and automatically adapt itself to slight irregularities in the surfaces of the valve or seat and prevent leakage from that cause.

By this simple attachment the operator can very easily and quickly control the flow of the water through the nozzle either to cut it off entirely or regulate the amount passing through the same.

The casing and other parts will generally be of brass, but may be of any other metal or metallic compounds, as may be preferred.

, A stop 23 in the casing 13 limits the movement of the valve to prevent it being moved too far in either direction. I

I claim In a device of the class described,a valve-cas ing provided with alined inlet and outlet ports and having threaded extensions at said ports for detachable connection With a nozzle and section of hose, respectively, said casing being closed at one end thereof and provided at its opposite end With a threaded cap, a conduit extending longitudinally through the casing and communicating With said .ports, a valvestem mounted for rotation in the closed end of the casing and having a valve formed of a CHARLES HENRY SMITH.
